The crank wheels were different on the YZ's I worked on. Maybe the owner has 2000 and 2001 models and doesn't know it.
It could be as easy as getting the correct bushings for the swingarm pivot like on the Honda CR's to swap motors into a later chassis..
That's good to know then, that it is the casting internals of the motor that are slightly different. You could probably find a 99 motor or bike cheap, and have a spare motor ready to go for different types of riding/racing.
